This uses explicit operators instead of intrinsic runtime calls to
create literals froms boilerplates. It allows for easier access of
static parameters and syncs it with other allocating operators.

If the array's map is the initial FastHoley array map, and the array prototype
chain is undisturbed and empty of elements, then keyed loads can convert the

Lolcode candidate: Both Expression and FunctionLiteral define an accessor is_parenthesized(), which access different flags. FunctionLiteral derives from Expression.

Given
      FunctionLiteral* a; a->is_parenthesized()
const FunctionLiteral* b; b->is_parenthesized()

the first accesses FunctionLiteral::IsParenthesized, the second accesses Expression::IsParenthesizedField.

Since these are distinct uses, we could rename them based on their use:
- Expression::is_parenthesized -> is_single_parenthesized
  Count # of parenthesis, for parsing & error handling:
  no parenthesis -> single parenthesis -> multi parenthesis
- FunctionLiteral::eager_compile_hint()
  Hint from parser to compiler about whether the parser suggests this function for eager compilation.

Now all nodes that care about deoptimization always take frame state
inputs no matter whether deoptimization is enabled for a particular
function. In case that deoptimization is off, the AstGraphBuilder just
inserts the empty frame state. This greatly simplifies the logic in
various places and makes testing easier as well, and is probably the
first step towards enabling --turbo-deoptimization by default.

There seems to be no noticable performance impact on asm.js programs.

Also fix the graph replay in order to regenerate the scheduler unittests.
